 For this case what you should know is that the area of a circle is given by:
 A = pi * r ^ 2
 Where,
 r: radio
 On the other hand we have:
 r = d / 2
 Where,
 d: diameter.
 Substituting:
 A = pi * (d / 2) ^ 2
 We note that the diameter of the circle is 58 ft
 Substituting:
 A = 3.14 * (58/2) ^ 2
 A = 2640.74 feet ^ 2
 Answer:
 The area of the entire circular region (including the flowerbed) is:
 2,640.74 ft 2
